Els fantasmes no toquen a la porta

Bear and Marmot are great friends and always play together. It's fun to hunt for treasure, or sing and dance like pop stars. But one afternoon Bear tells Marmot that he has invited Duck to play with them. No way! Marmot doesn't like Duck. She doesn't like Duck or any other animal that might intrude upon her exclusive friendship with Bear. So she decides to do what she must to prevent Duck from playing with them. And she really will do anything! What trouble will her crazy ideas cause? Perhaps in the end having friends won't turn about to be so bad, it might even be more fun than she imagined...
